The Shadow Thieves spoke a secret language known as Shadow Cant, which was an argot derived from the Northern dialect, from when the Shadow Thieves were based in Waterdeep. Shadow Cant included vocabulary from Amn, Tethyr, and the Underdark.[10]

The Cormanthan dialect was the version of Chondathan spoken in Cormyr, the Dalelands, and Sembia,[10] from Teshwave in the north to Proskur in the south, and from the Far Hills in the west to Elmwood in the east.[9]

Trade Pidgin was a mixture of Chondathan and other Thorass languages spoken in the Heartlands and around the Sea of Fallen Stars that integrated many military terms from Cormanthan after the invasion of the Grand Army of the Tuigan. The version of Trade Pidgin spoken around the Inner Sea was strongly influenced by Easting. The accent of the Heartlands speakers was so different from the accent of the Inner Sea speakers that the two groups had trouble understanding each other.[10]

↑ 2.02.1Since Chondathan was not described as a language when the "Speaking in Tongues" article was written, it is assumed that some of the Central Thorass languages listed in that article were in fact dialects of Chondathan, based on where Chondathan was said to be spoken in 3rd edition and later sources. Moreover, these dialects were never published as official languages anywhere else but in the "Speaking in Tongues" article. For these reasons, this wiki considers them dialects of Chondathan.
